Iso-scallop Toolpath Generation for Orthogonal Turn-Milling of Ruled Surfaces

摘要

This paper presents a new method of computing constant scallop height tool paths for orthogonal turn-milling of ruled surfaces.Indeed,the traditional tool path generation method in or-thogonal tum-milling leads to unevenly distributed scallop-height between adjacent toolpaths,which prevent from reaching the required quality.The proposed approach is adequate for orthogonal mill-turning whose toolpath topology is parallel-pattem or spiral-pattem and the constant scallop height is guaranteed by modifying the path-interval distance through adjustment of the offset dis-tance.The machining results obtained show that this method can reduce uneven distribution of scallop height.
